Array iteration methods summarized

While attempting to explain JavaScript's reduce method on arrays, conceptually, I came up with the following - hopefully it's helpful; happy to tweak it if anyone has suggestions.

Intro

JavaScript Arrays have lots of built in methods on their prototype. Some of them mutate - ie, they change the underlying array in-place. Luckily, most of them do not - they instead return an entirely distinct array. Since arrays are conceptually a contiguous list of items, it helps code clarity and maintainability a lot to be able to operate on them in a "functional" way. (I'll also insist on referring to an array as a "list" - although in some languages, List is a native data type, in JS and this post, I'm referring to the concept. Everywhere I use the word "list" you can assume I'm talking about a JS Array) This means, to perform a single operation on the list as a whole ("atomically"), and to return a new list - thus making it much simpler to think about both the old list and the new one, what they contain, and

Про токены, JSON Web Tokens (JWT), аутентификацию и авторизацию

Token-Based Authentication(JWT)

Preconditions:

В данной заметке рассматривается работа JWT с симметичным алгоритмом шифрования (HS256/HS384/HS512)

Основы:

Аутентификация(authentication, от греч. αὐθεντικός [authentikos] – реальный, подлинный; от αὐθέντης [authentes] – автор) - это процесс проверки учётных данных пользователя (логин/пароль). Проверка подлинности пользователя путём сравнения введённого им пароля с паролем, сохранённым в базе данных пользователей;

Авторизация(authorization — разрешение, уполномочивание) - это проверка прав пользователя на доступ к определенным ресурсам.

Introduction to Sequelize Migrations

What are Migrations

Just like how we use Git to version control source code, we use migrations to manage the state of our database schemas.

I'm not really sure what that means...

Imagine you're working on project with another developer, and you're both tasked with creating a specific part of an event planning application. Let's say you are in charge of creating the Users and your friend is going to create the Events.

Let's say you and your friend divided the work in a way so that neither of you will have to to use each other's code to finish your tasks. While you're working on your part of the application, you only really need to touch the Users table when you are working with the database.
